Softkey in the more format menu. Displays a polar format. Each point
on the polar format corresponds to a particular value of both
magnitude and phase. Quantities are read vectorally: the magnitude at
any point is determined by its displacement from the center (which has
zero value), and the phase by the angle counterclockwise from the
positive x-axis. Magnitude is scaled in a linear fashion, with the value
of the outer circle usually set to a ratio value of 1. Since there is no
frequency axis, frequency information is read from the markers.
Softkey in the port extensions menu. Toggle to ON if you want to
compensate for phase shift due to an extended measurement reference
plane.
See in Chapter 5 for more information.
